jackson-处理xml

jackson是springboot默认集成的json库,但是它不单单是json库,它还可以用来处理xml

依赖

需要单独引入jackson的xml格式化模块

<dependency>
	<groupId>com.fasterxml.jackson.dataformat</groupId>
	<artifactId>jackson-dataformat-xml</artifactId>
	<version>2.11.4</version>
</dependency>

使用

xml和json互相转换的流程都是先转换为java对象,然后再转为目标类型

XmlMapper

对应与转换json用的ObjectMapper

  • 默认配置

    XmlMapper xmlMapper = new XmlMapper();
    
  • 自定义配置

    XmlMapper.builder()
    	.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES,false)//忽略实体类没有对应属性,true抛异常
    	.serializationInclusion(JsonInclude.Include.NON_NULL)//忽略null
    	.propertyNamingStrategy(PropertyNamingStrategy.LOWER_CAMEL_CASE)//驼峰首字母小写
    	.build();
    

pojo转xml

Stringn userXml = xmlMapper.writeValueAsString(user)

xml转pojo

User userPojo = xmlMapper.readValue(userXml, User.class);
